Arma II OA DayZ error Session Ends

[Steels 0]

Well, i can't get to work my ARMA II OA and DayZ. I am using DayZLauncher. I did everything like the dude say in this video

. Before i deleted the .pbo files the game told me to do so i did it. And now i am getting an ''error'' that tells me Session Ends (translated from czech version of the game '' Relace Ukončena''. It worked very well before i reinstalled my windows cuz i screwed up whole system. If you know what to do please tell me what to do. I bought the game only cuz of the mod and now i am getting sick of fixing all the errors. Please halp meh. Thanks
